incassa.

To `all whom it may concern;

Be it known that I, CHARLES ALLEN, a. citize lof Germany, residing atNew York city, county and State of New York, have invented a new andImproved Bedstead, of which the following is a specification.

This invention relates to a bedstead ot. novel construction moreparticularly adapted for boat trave1,'as it will absorb vibrations andretain a substantially level position during lateral and longitudinalmotions of the vessel. I

In the accompanying drawing: Figure 1 is a longitudinal section of abedstead embodying my invention; Fig. 2 a. plan; Fig. 3 a cross sectionon line 3-3, Fig. 2; Fig. 4 an enlarged section on line 4 4, Fig. 3, andFig. 5 a detail of one of the spiral springs.

` To the legs 10 of the bedstead is secured a frame 11 provided withcross slats or bars 12. These bars support a number of spiral springs 13arranged in two longitudinal rows on opposite sides of the longitudinalaxisof the bed. Each spring 13 is provided with a head 14 into which istted a bulged pad 15 made preferably of rubber.

The bed bottom 16 which may be lined as at 17 is provided with twolongitudinal rails 18, which are likewise arranged on opposite sides ofthe bed axis, and are alined with springs 13. In this way the springpads 15v will obtain a bearing on the rails, and permit the bed bottom-16 to be freely tilted from side to side.

Each of the two end pieces 19 of the bedstead is provided between itstop rail and the corresponding rail of vtrame 11, with a centrallydisposed tubular casing 20. This casing slotted as at 22 for the passageof a gudgeon 23 extending axially outward trom the end rails of bedbottom 16. Gudgeon 23 is free to turnjjn a bearing 24, normally centeredwithin casing 2O and which 'is spring supported as well as springsuspended. With the construction shown, a lower; spring 25 extends frombearing 24 to the bottom ot casing 20, while an upper spring 2G extendsfrom the bearing to the to'p of such casing. The upper end of this topspring 26 may bey hooked to a screw ring 27 engaging the threaded upperend of casing 20, by which construction the assemblage ,of the parts isSpecification of Letters Patent.A

facilitated while the tension of both springs is regulable.

It will be seen that when the ship pitches or rolls, such movement willin great part be counteracted by the bed bottom, which is retained in asubstantially level position by the weight of the sleeper and hisinvoluntary effort to counterbalance the tilt of the ship. That is tosay during a rolling movement of the ship, the sleeper will maintain thebed bottom level by changing his lateral pressure and thus unevenlycompressing the right and left springs 13. During a pitching movementthe level position is maintained by changing the head and foot pressure,and thus compressing springs 25, 26

lunevenly on opposite ends of the bed.

l claim:

1. A bedstead provided with end pieces, spring controlled bearingsconnected thereto, a bed bottom pivoted to the bearings, and means foryieldingly supporting said bottom.

2. A bedstead provided with end pieces, tubular casings connectedthereto, springhung bearings movable within the casings, and aspring-supported bed bottom journaled in the bearings.

3. A bedstead provided with end pieces, tubular slotted casingsconnected thereto, bearings in the' casings, upper and lower springsconnected to the bearings, and a bed bottom having axially extendinggudgeons that project into the casings and are rotatable in thebearings. i

4. A bedstead provided with end pieces, slotted casings connectedthereto, bearings in the casings, screw rings tapped into the casings,springs connecting the bearings with said rings, and a bed bottom havingaxially extending gudgeons that project into the casings and arerotatable in the bearings.

5. A bedstead provided with a frame, spiral springs mounted thereon,bulged pads carried by the springs, a bed bottom supported by the pads,and having axially extending gudgeons, and spring-hung bearings engagedby the gudgeons.
